Now we repeat the process for the operational code and the FPGA code, using the same SET TFTP FILE_TYPE, SET TFTP FILE_NAME, DOWNLOAD INBAND sequence as for the boot code.

Once you have successfully downloaded the FPGA code for the base unit (that is, module 1) and for each module, you can use the SHOW MODULE VERBOSE command to check each module′s FPGA levels, as shown below:

￿			￿
	8285> show module 1 verbose
	.
	.
	.
	P/N:58G9605 S/N:LAG050
	EC level:C38846 Manufacture: 53-
	Operational FPGA version : 2
	Backup FPGA version : C10￿1￿
	8285> show module 2 verbose
	.
	.
	.
	ATM Carrier Module Information:
	--------------------------------
	P/N:51H3862 EC level:E28091	Manufacture:VIME
	Operational FPGA version : B3F3(BAD LEVEL)￿2￿
￿	Backup FPGA version : B40		￿

Note:

￿1￿C10 indicates that the correct FPGA code is in the backup FPGA, ready to be swapped.

Other possible values include:

•None indicating that no valid code is available to be swapped. This may occur on both the IBM 8285 Base Unit and the ATM

12-Port 25 Mbps UTP Concentrator Module. The correct action to take is to download the FPGA code for that module again. Do not proceed with swapping microcode until you have valid microcode in the backup FPGA for each module to be swapped.

￿2￿(BAD LEVEL) is indicated because the current and backup microcode levels are incompatible. Note that the correct code level is in the backup FPGA, ready to be loaded.

Please note that it is the backup FPGA that is updated, not the operational FPGA.
